[CCTECH] QBUS backplanes, potentially free for shipping

I will probably have some empty BA213 QBUS housings available free for shipping. I will know if I want to grab these if I find anyone interested in them and if I can find a box big enough to hold them as I have little use for them myself. One is a pedestal enclosure which orignally housed a DECserver 500 and features 12 slots of Q-CD goodness and a single H7868 power supply. I mention this because it appears that DEC shipped some sort variation of the 213 for the DECserver 500 which did not support a second power supply. The spot for the card edge backplane connector is there where the second H7868 would plug in but no connector is present. Obviously it would not be a big trick to rig some sort of separate power supply for drives or tapes. The other unit is from a rackmount DECserver 550 and appears to have a more normally configured BA213 with space for two working power supplies, although none are included. Either of these units might help give your QBUS Microvax some Q22 breathing room. On a related note, I recall that there was some ability to convert the KDJ11 module for this DECserver into a working PDP 11/xx (83+?) with a PROM swap? Does anyone know more about this and its feasibility?
